The 6oz square bottom Drosophila bottles are precision moulded from pure, virgin medical grade polypropylene. Polypropylene bottles are fully autoclavable and reusable, yet disposably priced. These high-quality bottles are thoughtfully designed with thin walls for the best visibility and graduation marks that are useful for pouring Drosophila media. The square bottom is designed with rounded edges, which means more surface area for fly food to form a tight seal that secures it in the bottom of the bottle making them extremely easy to use when flipping flies.

• Outstanding clarity
• Fully autoclavable
